    Detailed Description

    A raster consists of a matrix of cells (or pixels) organized into rows and columns (or a grid) where each cell contains a value representing information, such as temperature. Rasters are digital aerial photographs, imagery from satellites, digital pictures, or even scanned maps.

    It can be created from a raster file on device or from a raster function.

    Supported Raster formats include:

    • CIB1, 5, 10
    • DTED0, 1, 2
    • GeoTIFF
    • HFA
    • HRE
    • IMG
    • JPEG
    • JPEG 2000
    • NITF
    • PNG
    • RPF
    • SRTM1, 2
    • Mosaic Dataset in SQLite (read-only)

    Learn more about rasters from the ArcGIS Desktop documentation.

    This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.

    Property Documentation

    [read-only] error : Error

    Returns the error object (read-only).

    See also Loadable and Error.

    [read-only] loadError : Error

    Returns the load error (read-only).

    Note: load errors are also reported on the error property and emit the errorChanged signal.

    See also Loadable.

    [read-only] loadStatus : Enums.LoadStatus

    The Enums.LoadStatus of the Raster.

    See also Loadable and Enums.LoadStatus.

    path : url

    The path to the local raster image file.

    Note: You cannot set the path to the raster after the instance is already loaded.

    [default] rasterFunction : RasterFunction

    The raster function used to construct this Raster.

    [read-only, since Esri.ArcGISRuntime 100.1] rasterType : Enums.RasterType

    Returns the Raster type (read-only).

    This property was introduced in Esri.ArcGISRuntime 100.1.

    See also Enums.RasterType.
